Recycled Materials in Concrete

Following the implementation of a number of EU directives, especially the 1999 Landfill directive, the recycling industry is keen to develop new markets and products that will absorb the steel fibres produced from used tyres.

One possible market area for the recycled steel fibres is that of concrete construction, where industrially produced steel fibres are replacing re-bars in a range of applications, such as slabs-on-grade, industrial floors, precast applications and sprayed concrete.

The research, carried out by the CEE Group at the University of Sheffield, aims to investigate the behaviour of concrete reinforced with steel fibres, recycled from post-consumer tyres (RSF) and to develop innovative applications for the construction industry.

Research findings indicate that the use of RSF in concrete leads to an increase in concrete strength, ductility, and toughness and hence, RSF could be used in a range of specialised applications. International patent applications are pending.
